Sumiko Flux Buster Demagnetizer

Two Contributors have an experience of a Degauss on  MC Cart' and SUT and report back that a valuable impression has been made.

The Phasemation Degauss I have witnessed used, is sold as a MC and SUT Degauss device, I trust Phasemation as a Company, I have been quite impressed by other products from this company and don't doubt their product description.

All other contributions appear to be from a selection of individuals without a purpose produced plug in device to Degauss.

'Fe' is the magnetic element that is part of a Cores 'metal make up', in a multitude of Transformer Windings.

'Contempt Prior to Investigation' prevails.

The cartridge manufacturer VanDen Hul recommends NOT using this device.  They say that the first use will result in a dramatic improvement in sound, but, the effect will be short lived.  Subsequent will have to be quite frequent to maintain improvement, and in the long run, the sound will be degraded.  You can go to their FAQ section of their website for a more detailed explanation.

There is the chance the Degauss is not offering a ubiquitous treatment for all Cart's Coils and Tranx Coils.

Phasemation are extremely experienced in this area and I don't see a product being offered that will be reported back on as having a detrimental effect.

Sumiko are not having their first Rodeo either.  

@lewm I think that is a much more likely explanation. Rubber will take a set as you know from car tires. Demagnetization (which we use to do all the time for tape heads) requires use of a demagnetizer. This is a device that generates a very strong magnetic field that oscillates at line frequency changing poles at 60 Hz. You get it close to the tape head wave it around a little and slowly withdraw it from the head. The slowly weakening field oscillating at 60 Hz oscillates its way down to zero and whatever you pointed it at is demagnetized. I am not sure if this works with certain permanent magnets but it would seem to me to be a very dangerous thing to do with a cartridge. I think it is safe to say you are smarter than Stan given your history. 

I am going to get the test record if it is still available and record samples for comparison. See what gives. 

I've used the Sumiko Fluxbuster periodically for years and never had an issue with any MM or MC cartridge.
